“…Ovens were not available in Sumba for accurate measurement of DM content. Thus, DM intake (DMI) of bulls and the amount of legume offered daily was calculated by using DM values reported in the literature: clitoria, 25% DM (Nulik et al 2013); native grass, 25.8% DM (Quigley et al 2009); rice straw, 63.4% DM (Mayberry et al 2014). Feed conversion ratio was calculated by dividing average DMI by average daily LWG.…”

Context Increasing demand for livestock products in developing countries provides opportunities for smallholder farmers to increase and diversify their income through increased livestock production. However, livestock production in these systems is often limited by inadequate animal nutrition, and farmers need ways to increase the availability and quality of livestock feed without compromising yields of food crops or increasing the area of land planted to forages. Aim Using eastern Indonesia as a case study, we explore the potential for herbaceous legumes, integrated into existing mixed crop–livestock systems, to address specific production issues in smallholder beef systems. Methods Through a series of in-village feeding demonstrations, we tested three opportunities to increase livestock production through the use of herbaceous legumes: (i) increasing reproduction rates of cows by maintaining their liveweight (LW) and body condition score during the dry season; (ii) increasing the survival and LW gain of unweaned calves; and (iii) increasing LW gain of growing bulls. Key results Small amounts of legume (~10 g DM/kg LW) were enough to maintain LW of cows grazing poor-quality grasses and crop residues during the dry season. At higher levels of inclusion in the diet (~20 g DM/kg LW), feeding legumes increased the LW gain of growing cattle and survival of unweaned calves, providing benefits similar to a purchased concentrate, but at lower cost. Conclusions Our results demonstrate how strategic use of herbaceous legumes can increase beef production from low-input systems by maintaining LW of cows, and increasing survival of unweaned calves and LW gain of growing bulls. Implications Integration of herbaceous legumes into existing cropping systems removes many of the barriers to supplementary feeding. Improved livestock nutrition does not need to be based on purchased concentrates or increases in land used for forage production. The results are applicable to many other mixed crop–livestock systems throughout Southeast Asia.

“…These livestock models differ in their assumptions and approach (e.g., steady state and dynamic) to simulate cattle production systems [45]. However, one of the challenges inherent to most livestock simulation models used in the (Sub-)Tropics is still the errors associated with predictions of resource use (i.e., feed intake) and productive performance (e.g., BW gain) [5,9]. Hence, improving the adequacy (i.e., accuracy and precision) of predictions should continue to receive attention to ensure that the basis on which conclusions will be drawn from simulation outcomes is reliable.…”

“…Simulation models have often been used [2,4] to enhance researchers' knowledge on the feedforward and feedback interactions between different components (e.g., feed production, different animal herds, grazing land, and climate) of (sub-)tropical ruminant production systems. Such interactions are governed by biologically regulated processes (e.g., energy partitioning and use, feed intake regulation), which define the responses of ruminants to abiotic and biotic factors within a production system [5]. Ruminant production systems in the (Sub-)Tropics differ from those in temperate areas, for instance, in terms of the species or breeds of animals and their nutritional requirements [6,7], the availability and nutritional quality of feeds [8], and the prevalent environmental conditions.…”

Ruminant livestock systems in the (Sub-)Tropics differ from those in temperate areas. Yet, simulation models used to study resource use and productive performance in (sub-)tropical cattle production systems were mostly developed using data that quantify and characterize biological processes and their outcomes in cattle kept in temperate regions. Ergo, we selected the LIVestock SIMulator (LIVSIM) model, modified its cattle growth and lactation modules, adjusted the estimation of the animals’ metabolizable energy and protein requirements, and adopted a semi-mechanistic feed intake prediction model developed for (sub-)tropical stall-fed cattle. The original and modified LIVSIM were evaluated using a meta-dataset from stall-fed dairy cattle in Ethiopia, and the mean bias error (MBE), the root mean squared error of prediction (RMSEP), and the relative prediction error (RPE) were used to assess their accuracy. The modified LIVSIM provided more accurate predictions of voluntary dry matter intake, final body weights 140 days postpartum, and daily milk yields than the original LIVSIM, as shown by a lower MBE, RMSEP, and RPE. Therefore, using data that quantify and characterize biological processes from (sub-)tropical cattle production systems in simulation models used in the (Sub-)Tropics can considerably improve their accuracy.

“…Ingredients were purchased from local feed traders, and mixed at the Beef Cattle Research Institute in Grati, East Java. The ration was formulated using the Large Ruminant Nutrition System (LRNS) version 1.0.17, which is based on the Cornell Net Carbohydrate and Protein System (Fox et al 2004), and was evaluated for feeding Indonesian Ongole cattle (Mayberry et al 2014). According to LRNS formulation, the concentrate would provide 10.6 MJ metabolisable energy (ME) and 117 g crude protein (CP) per kg dry matter (DM).…”

Penambahan konsentrat pada ransum sapi jantan persilangan untuk meningkatkan keuntungan peternak sapi penggemukkan di Jawa Timur, Indonesia. JITV 20(1): 42-48. DOI: http://dx.doi.org/10. 14334/jitv.v20i1.1115 Tingkat pertumbuhan sapi pada system penggemukkan oleh peternak skala kecil secara umum masih rendah karena kebutuhan nutrisi kurang tercukupi. Penelitian ini bertujuan untuk membandingkan pertumbuhan sapi dan keuntungan peternak antara sapi jantan dengan pakan tradisional dan sapi jantan dengan pakan tambahan (suplemen) berupa konsentrat berkualitas tinggi. Penelitian ini dilakukan di dua lokasi di Jawa Timur yaitu Probolinggo dan Lamongan dengan menggunakan sapi jantan persilangan PO-Bos taurus berumur 1,5-2 tahun dari yang dibedakan menjadi 2 kelompok perlakuan, yaitu kelompok kontrol dan intervensi. Peternak pada kelompok intervensi, sapi jantan diberi pakan suplemen berupa campuran: onggok, kopra dan bungkil inti sawit. Peternak memberikan suplemen sebanyak 4 kg/ekor selama 161 hari atau sampai terjual. Managemen pakan pada kelompok kontrol adalah tetap (pola peternak). Umumnya peternak menggunakan hijauan lokal dan hasil samping pertanian sebagai pakan ternak, tanpa adanya suplementasi. Biaya pakan harian dan harga per 1 kg pertambahan bobot badan sapi lebih tinggi pada kelompok intervensi (Rp. 8.827 dan Rp. 11.990) daripada kelompok kontrol (Rp. 2.606 dan Rp. 5.543). Namun demikian, pertambahan bobot badan harian sapi jantan kelompok intervensi (0,82 kg/hari) lebih tinggi dibandingkan dengan kelompok kontrol (0,52 kg/hari), sehingga menghasilkan keuntungan yang lebih besar. Pendapatan harian dikurangi dengan biaya pakan pada peternak kelompok intervensi (Rp. 24.182/hari) lebih tinggi dibandingkan dengan kelompok kontrol (Rp. 5.774/hari). Dapat disimpulkan bahwa meskipun terdapat biaya tambahan untuk memberikan pakan berkualitas tinggi, namun dengan tingkat pertumbuhan sapi jantan yang tinggi menghasilkan keuntungan lebih besar pada peternak.

This study compared bull growth and farmer profit between two feeding management systems, namely traditional feeding (as control) and intervention feeding by supplementation with a high quality concentrate. Bos taurus-Ongole cross bred bulls (n=46) aged 1.5-2 years, owned by smallholder farmers, from two villages in East Java were used in this study. The bulls were divided into two treatment groups; control and intervention. Farmers in the intervention group were provided with a concentrate containing onggok, copra and palm kernel cake. Farmers were instructed to feed 4 kg DM of concentrate/bull/day in add...
